Description
Technical field
The present invention relates to LTE technology in the communications field, in particular it relates to the interoperability of self-organizing network
Method and device.
Background technology
Long Term Evolution (Long Term Evolution, the referred to as LTE) net of 3G (Third Generation) Moblie
Network is by universal land radio access web (the Evolved Universal Terrestrial Radio of evolution
Access Network, referred to as E-UTRAN) and block core (the Evolved Packet of evolution
Core, referred to as EPC) net composition.E-UTRAN comprise evolution base station (Evolved NodeB,
Referred to as eNB) set, EPC comprise mobile management entity (Mobile Management Entity,
Referred to as MME) and gateway (Serving Gateway, referred to as S-GW) etc., network rack
Structure flattening.Advanced LTE (LTE Advanced, referred to as LTE-A) system is by LTE system
System develops, and the network architecture is consistent with LTE.
In order to reduce the cost of networking and operation, the necessarily autogamy of the trend of next generation mobile networks
Put, self-optimizing and manual intervention less and less, therefore, it is proposed to self-organizing network
The concept of (Self-Organized Network, referred to as SON).
In LTE system, SON function is made up of three parts, i.e. self-configuring, self-optimizing and
From healing.The division of these three function is based on the duty of eNB.Fortune also it is introduced at eNB
Before row state, self installation and initial parameter configuration broadly fall into self-configuring process；Run when eNB enters
After state, automatically adjusting of systematic parameter belongs to self-optimizing process；When there is partial failure in eNB,
System carries out self-recoverage, now belongs to from healing process.
SON includes MLB, and (Mobility Load balancing optimization, mobility load is all
Weighing apparatus optimizes) and MRO (Mobility robustness optimization, mobile robustness optimization) skill
Art.
In a mobile network, handoff parameter arrange improper meeting has a strong impact on systematic function, Yi Jiyong
Family is experienced, and the most serious situation is to cause conversation loss.Therefore mobility parameters self-optimizing is LTE
One of system SON sixty-four dollar question to be solved, it to reach to reduce sending out of handoff failure
Raw, reduce the conversation loss that improper switching causes, and reduce unnecessary switching, it is to avoid these are cut
Change the invalid use to system resource.MRO function mainly solves to switch present in LTE network to ask
Topic and cell reselection problem, MRO is divided into Intra-LTE and Inter-LTE two large divisions, enters respectively
Mobility parameters optimization in row LTE system and LTE and other inter-system mobility parameter optimization.
MRO algorithm mainly by ceaselessly adjust Hysteresis (lag parameter, i.e. Hys) and
Two parameters of Time-to-trigger (Time Triggered parameter, TTT) reach the effect of handover optimization: fall
The switchings such as Radio Link Failure during low switching, handover failure rate, pingpang handoff rate, cutting off rate
Problem.
Owing to the unreasonable distribution of terminal can cause the load imbalance between different districts, the most permissible
Make terminal be transferred to other communities by congested cell by suitable network operation, thus improve network money
Source utilization rate.MLB mainly by the way of handoff parameter adjusts by a community (i.e. Serving cell)
Load transfer in neighbor cell.MLB mainly adjusts former community (i.e. Serving cell) and target
The cell Individual Offset (cell individual offsets parameter, Oc) of community (i.e. neighbor cell) reaches
Effect to MLB.
Can see from two SON processes of MRO and MLB and both can affect switching from different angles
Parameter.As a example by LTE handover event A3, the switching condition of A3 event is
Mn+Ofn+Ocn-Hys ＞ Mp+Ofp+Ocp+Off, wherein, Mn and Mp is neighbor cell respectively and services little
The RSRP (reference signal received power, Reference Signal Received Power) in district or RSRQ
(reference signal received quality Reference Signal Received Quality), Ocn and Ocp is respectively
It is the cell Individual Offset (cell individual offsets parameter, Oc) of neighbor cell and Serving cell,
Ofn (definite value) and Ofp (definite value) is that the offset Freq of neighbor cell and Serving cell is (inclined respectively
Shift frequency rate), Hys (definite value) is Hysteresis, and off (definite value) is a3-Offset.So A3
Event switching condition can be abbreviated as Mn+Ocn-Hys ＞ Mp+Ocp:
MRO revises TTT and Hys → 1.Mn+Ocn-Hys ＞ Mp+Ocp, 2. amendment TTT；
MLB revises Ocn and Ocp → Mn+Ocn-Hys ＞ Mp+Ocp；
Can be seen that another one opens during MRO and MLB starts or work as the execution of a function
Time dynamic, above-mentioned functions can clash, and causes without corresponding strategy interoperability process: user
Cutting off rate improve, it is not necessary to pingpang handoff, handover failure rate improve, affect Consumer's Experience.

In technique scheme, also include before amendment mobility load balance optimization handoff parameter:
Serving cell determines that this community is transshipped.
In technique scheme, amendment mobility load balance optimization handoff parameter specifically includes amendment
Cell individual offsets parameter in mobility load balance optimization handoff parameter.
Fig. 1 is the schematic flow sheet of the self-organizing network mutual operation method according to the embodiment of the present invention one,
Two functions of MRO and MLB in the present embodiment need simultaneously in Serving cell and neighbor cell it
Between realize, the present embodiment includes:
Step 102: Serving cell and neighbor cell first exchange the handoff parameter of MLB and MRO, cut
Change parameter and specifically include that lag parameter Hys, cell individual offsets parameter Ocn of neighbor cell, clothes
Cell individual offsets parameter Ocp of business community and Time Triggered parameter TTT etc.；
Step 104: each Serving cell can periodically broadcast the load information of oneself in LTE
To the neighbor cell of self, if this Serving cell overload, it can make load all to neighbor cell request
Weighing apparatus, load balancing is to be switched by UE (User Equipment, user terminal) group, and group's switching can
Completed by amendment cell individual offsets parameter；
According to the loading condition of Serving cell, after Serving cell amendment Ocp parameter, Serving cell can be
The load information storehouse of self updates Ocp parameter, after Serving cell can will update in load information storehouse
Ocp parameter issues neighbor cell, the Ocp parameter that neighbor cell sends according to Serving cell, and amendment is certainly
The Ocn parameter of body；As a example by A3 event: neighbor cell receives Serving cell amended Ocp ginseng
After number, neighbor cell can select for arranging UE in the inner, the inequality that self is interior
The Ocn parameter that Mn+Ofn+Ocn-Hys ＞ Mp+Ofp+Ocp+Off can set up, wherein, in above-mentioned inequality
Ocp parameter is the parameter of Serving cell, and Ocn parameter is the parameter of neighbor cell；
Then, amended Ocn parameter is sent to Serving cell by neighbor cell, and Serving cell will connect
The Ocn parameter received substitutes in the inequality Mn+Ofn+Ocn-Hys ＞ Mp+Ofp+Ocp+Off of self, wherein, on
Stating the parameter that Ocp parameter is Serving cell in inequality, Ocn parameter is the parameter of neighbor cell；
If now this inequality is set up, then step 104 completes；
If now this inequality is false, Serving cell is ensureing inequality
Mn+Ofn+Ocn-Hys ＞ Mp+Ofp+Ocp+Off continues amendment parameter Ocp in the case of setting up, simultaneously by self
Ocp in load information storehouse updates, then the Ocp parameter after updating in load information storehouse is issued adjacent
Community, after neighbor cell receives Serving cell amended Ocp parameter, continues to select for being arranged at
For its interior UE, self interior inequality Mn+Ofn+Ocn-Hys ＞ Mp+Ofp+Ocp+Off can set up
Ocn parameter, is sent to Serving cell by amended Ocn parameter the most again；
Whether set up by the inequality Mn+Ofn+Ocn-Hys ＞ Mp+Ofp+Ocp+Off of Serving cell checking self,
If set up, then step 104 completes, and otherwise, continues amendment Ocp parameter；With this reciprocation cycle,
Until in Serving cell and neighbor cell, inequality Mn+Ofn+Ocn-Hys ＞ Mp+Ofp+Ocp+Off sets up,
Step 104 completes, as shown in Figure 1.
It should be noted that at step 104, in Ocp parameter in Serving cell and neighbor cell
The last amendment result of Ocn parameter need no matter in Serving cell or in neighbor cell, no
Equation Mn+Ofn+Ocn-Hys ＞ Mp+Ofp+Ocp+Off sets up.
Specifically, at step 104, amendment Ocn and Ocp is just Serving cell and neighbor cell
Between switching take to Serving cell expand, therefore some does not possess the UE of switching condition, amendment
After the parameters such as Ocn and Ocp, just meet the condition being switched to neighbor cell.
Step 106: set a threshold value, if occurring in neighbor cell that a large number of users terminal is switched to
Serving cell, and when quantity exceedes this threshold value, then need to revise lag parameter Hys etc. by a relatively large margin
The handoff parameter of MRO, the most slightly revises；
(such as neighbor cell occurs according to the user's situation of movement between Serving cell and neighbor cell
A large number of users terminal is switched to the situation of Serving cell), handoff parameter Ocp, Ocn, Serving cell
The handoff parameter of the MRO such as lag parameter Hys is revised, as shown in Figure 2 with neighbor cell；
Such as: assume to revise the UE1 of Serving cell before Ocn and Ocp and be unsatisfactory for being switched to adjacent
The condition of community, after modified Ocn and Ocp, UE1 is the most satisfied is switched to neighbor cell
Condition.But, although UE1 meets switching condition, MRO function need ensure UE1 switching after not
Radio Link Failure or pingpang handoff etc. can be occurred to switch abnormal problem；In order to send out after ensureing switching
The raw switching abnormal problem such as Radio Link Failure or pingpang handoff, MRO may need to revise Hys.
It should be noted that as a example by A3 event, the amendment MRO parameter of this step 106 is
Rear result also needs to meet the condition that inequality Mn+Ofn+Ocn-Hys ＞ Mp+Ofp+Ocp+Off sets up.
Step 108:eNB allows UE (i.e. use by the way of newly-increased signaling or renewal measure configuration
Family terminal) report handover measurement, such as, it is all little in service that eNB can descend signaling allow at any time
UE in district and neighbor cell measures and reports handover measurement to report；
Step 110:UE measures Serving cell and RSRP (the reference signal of neighbor cell
Received power, Reference Signal Received Power) or RSRQ (reference signal received
Quality, Reference Signal Received Quality), and measurement result is reported Serving cell；
(1) Serving cell judges that the user of neighbor cell to be switched to meets switching condition；
If RSRP, RSRQ of user terminal meets or close to handoff threshold condition, service at present
Community may determine that user terminal to be removed in neighbor cell meets switching condition.
(2) neighbor cell and/or Serving cell judge to be switched to the user of neighbor cell from Serving cell
It is resident whether terminal can be stablized in neighbor cell, and in other words, can neighbor cell judges stable
Service is provided for being switched to the user of neighbor cell from Serving cell；
In (2), it is similar to the Serving cell in (1), the Serving cell of UE and neighbor cell
RSRP, RSRQ suitable time pingpang handoff can occur, if handover parameter values arrange excessive or
The too small problem that pingpang handoff or switching too early also can occur, if Serving cell and neighbor cell occur
The probability of pingpang handoff is higher, then user terminal can be stablized resident in neighbor cell；
Step 112: if the condition in step 110 (1) is unsatisfactory for, then Serving cell and adjacent little
Respective MLB handoff parameter is revised in district again, until condition (1) meets；
If the condition in step 110 (2) is unsatisfactory for, then amendment MRO handoff parameter, until bar
Part (2) meets；Condition (2) ungratified reason may have multiple, and some reasons need to service little
District's amendment MRO parameter, some reasons need neighbor cell amendment MRO operation；
If the condition in step 110 (1) and (2) meet simultaneously, then start the operation of MLB.
In step 112, as an embodiment, when above-mentioned condition (1) meets, service little
District can be by meeting the information reporting of condition (1) to OAM (being similar to network management system), above-mentioned
When condition (2) meets, neighbor cell can will meet the information reporting of condition (2) to OAM,
OAM triggers MLB operation.
Such as: as a example by A3 event: the measurement result that UE reports includes service and neighbor cell
RSRP and RSRQ, through MLB handoff parameter and the MRO switching of step 104 and step 106
After the amendment of parameter, inevitably result in the change of the handover measurement that UE measures, and
The change of handover measurement can cause handover event inequality Mn+Ofn+Ocn-Hys ＞ Mp+Ofp+Ocp+Off
Change, wherein, Mn and Mp is RSRP or RSRQ of neighbor cell and Serving cell respectively,
So for UE, the handoff parameter revising above-mentioned Mn and Mp can directly result in handover event not
Equation changes.Handover event inequality changes and UE can be caused to determine whether switching cell；
Therefore in A3 event, after revising the handoff parameter of above-mentioned Mn and Mp, at handover event not
In the case of equation Mn+Ofn+Ocn-Hys ＞ Mp+Ofp+Ocp+Off sets up, start Serving cell in step 112
Operation with the MLB of neighbor cell.
According to embodiments of the present invention, it is provided that the mutual operation method of another kind of self-organizing network, this enforcement
Two functions of MRO and MLB in example need to realize between Serving cell and neighbor cell simultaneously,
The present embodiment includes:
Step 202: Serving cell and neighbor cell first exchange the handoff parameter of MLB and MRO, cut
Change parameter and specifically include that lag parameter Hys, cell individual offsets parameter Ocn of neighbor cell, clothes
Cell individual offsets parameter Ocp of business community and Time Triggered parameter TTT etc.；
Step 204: set a threshold value, if occurring in neighbor cell that a large number of users terminal is switched to
Serving cell, and when quantity exceedes this threshold value, then need to revise lag parameter Hys etc. by a relatively large margin
The handoff parameter of MRO, the most slightly revises；According between Serving cell and neighbor cell
User's situation of movement (occurs in such as neighbor cell that a large number of users terminal is switched to the feelings of Serving cell
Condition), handoff parameter Ocp, Ocn, Serving cell and the neighbor cell amendment MRO such as lag parameter Hys
Handoff parameter.
Step 206: each Serving cell can periodically broadcast the load information of oneself in LTE
To the neighbor cell of self, if this Serving cell overload, it can make load all to neighbor cell request
Weighing apparatus, load balancing is to be switched by UE (User Equipment, user terminal) group, and group's switching can
Completed by amendment cell individual offsets parameter；
According to the loading condition of Serving cell, after Serving cell amendment Ocp parameter, Serving cell can be
The load information storehouse of self updates Ocp parameter, after Serving cell can will update in load information storehouse
Ocp parameter issues neighbor cell, the Ocp parameter that neighbor cell sends according to Serving cell, and amendment is certainly
The Ocn parameter of body；As a example by A3 event: neighbor cell receives Serving cell amended Ocp value
After, neighbor cell can select for UE, and inequality Mn+Ofn+Ocn-Hys ＞ Mp+Ofp+Ocp+Off can
With the Ocn parameter set up, wherein, the parameter that Ocp parameter is Serving cell in above-mentioned inequality,
Ocn parameter is the parameter of neighbor cell；
Then, amended Ocn parameter is sent to Serving cell by neighbor cell, and Serving cell will connect
The Ocn parameter received substitutes in inequality Mn+Ofn+Ocn-Hys ＞ Mp+Ofp+Ocp+Off, wherein, above-mentioned
The parameter that Ocp parameter is Serving cell in formula, Ocn parameter is the parameter of neighbor cell；If this
Time this inequality set up, then step 206 completes；
If now this inequality is false, Serving cell is ensureing inequality
Mn+Ofn+Ocn-Hys ＞ Mp+Ofp+Ocp+Off continues amendment parameter Ocp in the case of setting up, simultaneously by self
Ocp in load information storehouse updates, then the Ocp parameter after updating in load information storehouse is issued adjacent
Community, after neighbor cell receives Serving cell amended Ocp parameter, continues to select for UE,
The Ocn parameter that inequality Mn+Ofn+Ocn-Hys ＞ Mp+Ofp+Ocp+Off can set up, after revising the most again
Ocn parameter be sent to Serving cell；
Being verified whether above-mentioned inequality is set up by Serving cell, if set up, then step 206 completes,
Otherwise, amendment Ocp parameter is continued；With this reciprocation cycle, until in Serving cell and neighbor cell,
Inequality Mn+Ofn+Ocn-Hys ＞ Mp+Ofp+Ocp+Off sets up, and step 206 completes, as shown in Figure 1.
It should be noted that in step 206, in Ocp parameter in Serving cell and neighbor cell
The last amendment result of Ocn parameter need in Serving cell or in neighbor cell all
Inequality Mn+Ofn+Ocn-Hys ＞ Mp+Ofp+Ocp+Off to be made sets up.
Step 208:eNB allows UE (i.e. use by the way of newly-increased signaling or renewal measure configuration
Family terminal) report handover measurement, such as, it is all little in service that eNB can descend signaling allow at any time
UE in district and neighbor cell measures and reports handover measurement to report；
Step 210:UE measures Serving cell and RSRP (the reference signal of neighbor cell
Received power, Reference Signal Received Power) or RSRQ (reference signal received
Quality, Reference Signal Received Quality), and measurement result is reported Serving cell；
(1) Serving cell judges that the user of neighbor cell to be switched to meets switching condition；
If RSRP, RSRQ of user terminal meets or close to handoff threshold condition, service at present
Community may determine that user terminal to be removed in neighbor cell meets switching condition.
(2) neighbor cell and/or Serving cell judge to be switched to the user of neighbor cell from Serving cell
It is resident whether terminal can be stablized in neighbor cell, and in other words, can neighbor cell judges stable
Service is provided for being switched to the user of neighbor cell from Serving cell；
In (2), it is similar to the Serving cell in (1), the Serving cell of UE and neighbor cell
RSRP, RSRQ suitable time pingpang handoff can occur, if handover parameter values arrange excessive or
The too small problem that pingpang handoff or switching too early also can occur, if Serving cell and neighbor cell occur
The probability of pingpang handoff is higher, then user terminal can be stablized resident in neighbor cell；
Step 212: if the condition in step 210 (1) is unsatisfactory for, then Serving cell and adjacent little
Respective MLB handoff parameter is revised in district again, until condition (1) meets；
If the condition in step 210 (2) is unsatisfactory for, then amendment MRO handoff parameter, until bar
Part (2) meets；Condition (2) ungratified reason may have multiple, and some reasons need to service little
District's amendment MRO parameter, some reasons need neighbor cell amendment MRO operation.
If the condition in step 210 (1) and (2) meet simultaneously, then start the operation of MLB.
In the step 212, as an embodiment, when above-mentioned condition (1) meets, service little
District can be by meeting the information reporting of condition (1) to OAM (being similar to network management system), above-mentioned
When condition (2) meets, neighbor cell can will meet the information reporting of condition (2) to OAM,
OAM triggers MLB operation.
Such as: as a example by A3 event: the measurement result that UE reports includes service and neighbor cell
RSRP and RSRQ, through MRO handoff parameter and the MLB switching of step 204 and step 206
After the amendment of parameter, inevitably result in the change of handover measurement that UE measures, and handover measurement
The change of result can cause the change of handover event inequality Mn+Ofn+Ocn-Hys ＞ Mp+Ofp+Ocp+Off, its
In, Mn and Mp is RSRP or RSRQ of neighbor cell and Serving cell respectively, so to UE
For, revise the handoff parameter of above-mentioned Mn and Mp and can directly result in handover event inequality and become
Change.Handover event inequality changes and UE can be caused to determine whether switching cell；Therefore in A3 thing
In part, after revising the handoff parameter of above-mentioned Mn and Mp, at handover event inequality
In the case of Mn+Ofn+Ocn-Hys ＞ Mp+Ofp+Ocp+Off sets up, start Serving cell and phase in step 212
The operation of the MLB of adjacent cell.
It should be noted that the embodiment one of the mutual operation method of self-organizing network of the present invention and embodiment
The step 106 of two and step 204 are the preferred steps of embodiment, if occurring a large amount of in neighbor cell
Mobile terminal is switched to the situation of Serving cell, then perform step 106 or 204, otherwise, do not perform
Step 106 or 204.
It should be noted that the embodiment one of the mutual operation method of self-organizing network of the present invention and embodiment
Two only exist the different of priority execution sequence between step 104-106 from step 204-206: in reality
Execute in example one, first performed to revise the operation of MLB handoff parameter by step 104, then by step 106
